Book Description
Le cadre défini pour cette recherche dessine un polygone très irrégulier qui entoure le lac Tchad et couvre environ 60 000 krn2 chevauchant les frontières du Tchad, du Niger, du Nigéria et du Cameroun. On estimait en 1976 à 700 000 personnes la population qui vivait dans cet espace. L'étude descriptive régionale classique constitue le corps de l'ouvrage : le Bas-Chari, les Iles du lac, les péninsules du Kanem, le Sud-Manga et le Nord-Est du Bornu, sont présentés dans les plus infimes détails selon le style monographique. Entourant cette partie centrale, deux grands thèmes de réflexion abordent successivement la subjectivité de la perception spatiale dans une première partie, qui traite aussi bien de la géographie physique que de l'histoire, et les difficultés de la géographie thématique dans une troisième partie qui repose sur un exercice de changements d'échelle.

Book Description
This art book contains over 350 color photographs by Marzio Marzot, documenting information on traditional food production systems, scientific details and notes from a journey through one of the world' s outstanding region: the Lake Chad Basin in Africa. It provides an insight into the life and customs of the local farmers, fishermen and pastoralists who foster, maintain and utilize biodiversity in their traditional agricultural systems, thereby deploying the knowledge and techniques that they have accumulated over many centuries. FAO promotes the sharing of experiences and awareness related to the role of rural people in conserving and sustainably using agricultural biodiversity. Building on the local knowledge and social organization of farmers is indispensable. The images in this book are a tribute to the knowledge and work of farmers and their care for the land.

Book Description
This book investigates the ways in which people in the Lake Chad region that divides Nigeria, Niger, Chad, and Cameroon deal with the crises of violence, jihadism, drought, and climate change that continue to afflict the area. In 2014 Boko Haram expanded into the Lake Chad region, prompting a counter-insurgency response, and exacerbating pre-existing social and ecological challenges. Drawing on extensive ethnographic research, this book investigates how people within the liminal space of this key border region respond to and navigate the unpredictability which typifies their day-to-day lives. Building up a picture of individual and community experiences of crisis, the book gradually demonstrates the complex interactions between economic circuits, political orders, socio-religious processes, and labour practices which operate in the region. This book will be of interest to researchers across African studies, security studies, political science, and border studies.

Book Description
Comment le bassin du lac Tchad, espace hydrographique, plus connu pour son potentiel dé¬ citaire en ressources hydriques et la précarité de son écosystème, est-il devenu l'un des plus grands foyers africains d'instabilité ? Voilà la question à laquelle l'auteur tente d'apporter une réponse précise à travers l'analyse des éléments qui structurent le théâtre géostratégique du bassin du lac Tchad. Sans sombrer dans un déterminisme géographique, il montre que la géostratégie du bassin du lac Tchad est travaillée et traversée par une intrication des facteurs statiques et dynamiques. Au terme de ce travail qui a nécessité une introspection dans les champs disciplinaires de la stratégie, de l'anthropologie, de la sociologie, de l'histoire et de la géographie, le bassin du lac Tchad apparait comme un théâtre géostratégique singulier.
